[JLM]

Have moved up and no longer need.  Enjoyed nearly all its functions for 3 years.  Packed with features in a compact form, easy to set-up, and very pleasant sounding.  In pristine condition (used in man cave with no smoking, pets, or kids), fully functional, with all accessories.  Paid $900 USD, will sell for $400 USD delivered (in original packaging) to the lower 48.

Was my DAC/preamp fed by 10ft. USB and cheap 35ft. optical cables without a problem.  Connections on the back are tight, but doable.  Remote is cheap but never felt a pressing need to try a universal.  Made use of the bass DSP (highly recommended).  Tried CIA power supply in place of the wall wart (not included) but found little improvement, YMMV.  Thanks for looking.
